Surgeons simulate an operation wearing space costumes and standing inside a sterile room. The equipment was developed by Martin Marietta Corp. under a NASA contract, to produce conditions for sterile spacecraft assembly and self-contained life-support systems. A 10 by 10 foot perspex and aluminium room (a "laminar flow clean room") fits inside an operating room when in use. When not in use it can be folded and stored
